If your device is connected to the internet, the manual is then available for viewing right within the app. You can also store manuals for offline viewing either within Lighting Handbook or in your favourite PDF viewing app.

The library of manufacturers can be updated from within the app - Go to the settings menu, from there you'll be able to see what version of the library is currently installed and if connected to the internet, what version is now available for download. Click the "Update Library" Button and it will download the latest library and install into Lighting Handbook.

If you have a specific manufacturer or light you'd like including, please e-mail me and I'll try and include it in the next update.
